Pakistani terrorist Mohammed Ajmal Amir Qasab, who has been awarded death penalty for his role in the 26/11 terror attacks, is bidding his time by practicing karate in the high-security Arthur Road jail here, police sources said on Wednesday.

"Qasab does exercise and practises karate sometimes to kill his time. He also often strikes a conversation with the security guards deployed there to guard him round the clock," said a jail official. The terrorist appears to be knowing karate kicks very well, the official said.
